ANSWER

Students = 110

Teachers = 22

EXPLANATION

Let the number of students be s.

Let the number of teachers be t.

There are 5 times as many students as teachers. This means that:

[tex]\begin{gathered} s=5\cdot t \\ s=5t \end{gathered}[/tex]

The sum of students and teachers is 132. This means that:

[tex]s+t=132[/tex]

We can solve this by substitution. To do this, substitute the first equation into the second.

That is:

[tex]\begin{gathered} 5t+t=132 \\ 6t=132 \\ \text{Divide both sides by 6:} \\ \frac{6t}{6}=\frac{132}{6} \\ t=22 \end{gathered}[/tex]

Recall that:

[tex]\begin{gathered} s=5t \\ \Rightarrow s=5\cdot22 \\ s=110 \end{gathered}[/tex]

Therefore, there are 110 students and 22 teachers.
